  1. Clear trouble codes as needed. See BODY CONTROL COMPUTER - INTRODUCTION article. Using scan tool, read driver's door zone switch voltage. If DRIVER DOOR ZONE SWITCH voltage is about 4 volts, inspect driver's door key lock. Replace key lock as needed. If DRIVER DOOR ZONE SWITCH voltage is not about 4 volts, go to next step.
  2. Turn driver's door key cylinder switch to lock position and observe voltage on scan tool. Do not hold key in lock position for more than 7 seconds or code will set. If DRIVER DOOR ZONE SWITCH voltage is about 4 volts, go to next step. If DRIVER DOOR ZONE SWITCH voltage is not about 4 volts, replace driver's door key cylinder switch.
  3. Operate driver's door key lock cylinder several times from unlock to lock position. Release key lock cylinder. With key lock cylinder in neutral position, observe scan tool voltage. If DRIVER DOOR ZONE SWITCH voltage is about 5 volts, system is currently functioning correctly. If DRIVER DOOR ZONE SWITCH voltage is not about 5 volts, replace driver's door key cylinder switch.
